Effects of Testing Temperatures and Thermal Treatments on Flexural Strength of Si3N4‐MoSi2‐BN Composites
Source abstract
Abstract
The machinability of ceramic materials can be improved by the addition of hexagonal‐BN. Si3N4/h‐BN composites are suitable as rotor seals for gas turbine engines in the ranges 1000°C–1300°C. Oxidation resistance and strength retention can be improved by the addition of MoSi2 up to 1500°C. Strength retention is due to the formation of a surface borosilicatic glassy phase and the partially oxidized sub‐surface region which prevent extensive bulk damage.
